¡¡cuidado!! puede agrandar las prostata? consulte medico

Posted by iber13 on Dec 13, 2014

llevo tomándolo unos 30 días y apenas noto nada..seguiré e informare. Observo que de noche me levanto mas a mear (antes de comprar ver- estudiar el apartado medico de iherb sobre disfuncion erectil) creo que esta claro que en el normal desarrollo de envejecimiento -cualquier causa eréctil por otro lado normal con la edad aunque no tiene porque haberla- este producto no se debería tomar pues puede según el estudio tener contra indicaciones..la testosterona aumenta significativamente el volumen de la próstata-otros estudios dicen que funcionan mejor y existen otros fármacos apropiados-relacionados con el problema eréctil y que tienen mucho que ver con la relajación . Dejo de tomarlos.

Very good, but didn't like teenage acne!

Posted by 4758919319177831406 on Nov 17, 2014

I liked these. Nice boost in mood, and definitely elevated energy and libido levels. It needed about 3-5 days of consistent use before you start to notice things. I even got to a point where I noticed that certain male responses were increasing in turgidity and activity. At first, I was pretty psyched. However, then I noticed that I started getting a few pimples on my head and scalp, reminiscent of my teen years! Yeah, that wasn't fun. No other supplement I've taken had that side effect on me.. I also noticed that I was starting to have some evenings where I had a difficult time falling asleep. That was a bummer for me. I reduced to only taking one a day every once in a while when I need a boost. Really good stuff though. I wish I didn't get acne as a side effect. Your mileage may (and will likely) vary, as we all respond differently to these supplements. Try it out. Start with one for a few days, then increase to two.
